The D2 beta is a stress test, it's to test their server effectiveness but it's also letting you try the basic gameplay. The farm was empty for a reason and as I stated before the farm was released empty and for an hour was to jam pack as many people in one space to see how their servers hold up. The D1 beta was larger content wise, yes, but it also let you play the first half of the game. The D2 beta allows more mystery and suspense.
